We have two AppleTV units. One is HD and the other 4K. We’ve had Tablo for about a year now and worked well until a couple months ago. You are watching live tv or even a recording and the app with just close. . .No errors just crash. Opens just fine again and runs for a while.
I bought a Roku stick and Tablo is stable. I assume there is an issue with the Tablo app probably due to an AppleTV update
It may be wishful thinking but it seems better recently. It still crashes but seems less frequent the last couple weeks. Was there an update to the AppleTV app ?
